The canvassers, or one of them, shall prepare a list of the names of the parties designated as aforesaid, and to whom such notice has been sent, given, or left at the address, and make and attach his or their affidavit or affidavits thereto, stating that notice, duly stamped, was mailed to each of said parties at the places designated on the list, on or before 10 o'clock p. m. of the Thursday following the canvass, and that notice was also personally left at the said address of each of the parties named in the lists so attached, if there be such address; and such canvassers shall also file in the office of the Board of Election Commissioners on or before 6 o'clock p. m. on the Friday following the canvass, an exact duplicate of such list with the affidavit or affidavits attached thereto. Blank affidavit forms shall be furnished by the board for the purpose aforesaid; but if none are furnished, such canvassers shall cause the same to be drawn, and they shall swear to such affidavit before the judge of registration of such precinct, or a member of the Board of Election Commissioners, or the executive director thereof.
In cities, villages and incorporated towns having a population of over 200,000 and having a Board of Election Commissioners and in cities, villages and incorporated towns within the jurisdiction of the Board of Election Commissioners, the Board of Election Commissioners shall remain in session from 10 o'clock a.m. to 9 o'clock p.m. for 10 days following the last day of the canvass for the sole purpose of revising their registry. No new name shall be added to the registry at such session of the Board of Election Commissioners.
In cities, villages and incorporated towns having a population of less than 200,000, the hearing herein provided and the final revision of the registry, shall be by the Board of Election Commissioners for such city, village or incorporated town. The commissioners shall meet for this purpose upon the Monday and Tuesday following the canvass, and shall remain in session between the hours of 8 o'clock a.m. and 10 o'clock p.m., and the precinct election officials who made the canvass of the precinct shall meet with them as may be required by the Board of Election Commissioners.
If any person to whom such notice has been sent, shall appear before the Board of Election Commissioners during the session, he shall make oath and sign an affidavit in substance as follows:
"I do solemnly swear that I am a citizen of the United States and that I have resided in the .... precinct of the .... Ward of the City of ...., in the State of Illinois, since the .... day of ....; and that I have never been convicted of any crime (or if convicted, state the time and when pardoned by the Governor of any State)."
This affidavit shall be signed and sworn to before one of such Board of Election Commissioners, or the clerk of the board, and it shall be filed in the office of the Board of Election Commissioners and be preserved for 60 days.
Thereupon the Board of Election Commissioners shall further examine him and shall also swear such canvassers or the precinct election officials as the case may be, and hear them upon the question, and the Board of Election Commissioners shall have the power to send one or both of the canvassers or precinct election officials, as the case may be, to make further examination and inquiry at the place claimed by such person to be his residence, and again examine such canvassers or precinct election officials touching the same; and if after such further examination and hearing, the majority of the board in question are of the opinion that such person is not a qualified voter in such precinct, they shall indicate in the proper manner that the card of such person shall be removed from the precinct file.
At the close of any such session, if any person so notified to appear at such session has not appeared and shown cause why the card bearing his name should not be withdrawn from the precinct file, the same shall be withdrawn from the file.
The Board of Election Commissioners shall, however, keep the cancelled cards in a suspense file for 2 years and reinstate them at any time within such 2 year suspense period, when a person's registration is cancelled under this or other Sections of this Article for failure to apply for reinstatement or to appear in proper time, and there is sufficient subsequent showing that he is a duly qualified elector.
Either of said canvassers shall have the power and right of both in the matter pertaining to such canvass; but in case either refuses or neglects to make such canvass as aforesaid, then the other may make such canvass alone.
In case of the temporary disability upon the part of either canvasser, the remaining canvasser shall appoint a temporary canvasser who shall represent and be affiliated with the same political party as the canvasser whose place is being filled, and shall administer to him the usual oath of office for canvassers. Such temporary canvasser shall perform all the duties of the office until the disability of the regular canvasser is removed.
